--> Javelin will be "unsafe" for a longer time while controlling her rocket
--> longer charge should prevent Javelin to use her rocket in 1V1 , or in enemy's sight.
--> dmg increased on EV : i'm pretty sure Nader is now better at destroying EV and Javelin being better than Nader as Assault lul

It's very easy gun. Tab and shoot. IF you don't understand that it's easier to hit one front damage shot than continuosly track opponent during that same second you are completely out of your depth in the discussion and have no say in this matter.
This includes you and Amerika now. Both are based into that just stupid since you can somehow think that.

Especially player from CSgo where first shot matters a lot will love bursts. TTK is crazy short.

No.
Csgo gameplay is totally different from DirtyBomb ,
in DB , players are more mobile ( wall jump / rapid strafe ...) making players more difficult to hit ESPECIALLY with Burst rifles because you have to predict opponent's movements at a precise moment ( when you shoot your burst) , while with an automatic rifle you'r constantly trying to correct your "errors of prediction".
And TTK with burst in DB seems great but the time between each burst AND the delay between each bullet are a real handicap.
You don't always land the three bullets and sometimes leaves someones with 1-5% of life because you did'nt have the time to land the next burst.

It's just basic physics and maths...

Complaining about burst rifles nowadays is like complaing about being oneshot by Fel-ix or MOA in heashot. You just need to be more mobile.
Btw i loved Dreiss before his nerf/buff , now it's one of the hardest weapon to use , but still highly rewarding.

For me Sparks is currently well balanced , she is the most difficult medic but highly rewarding when well played. Lot of people cry about Sparks healing herself...what about Aura staying close to her healing station and facing assault rifle owners with ease ? ( heal station hidden by a wall ofc ) .
A good player with M4 / Timik kill Sparks before she put his medpack on the ground...and there is a small cooldown between each medpack put on the ground ( maybe 1sec ) , if you'r not able to do more than 40 dmg per second....your aim is bad.
